PHONOGBAPH ATTACHBIENT.

Specification of Letters Patent.

Application filed Novcmher29, 1913, Serial No. 803,762.

To all whom it may concern:

Be it known that I, ALBEn'r H l nrssn fo, a citizen of the United States, residing at New York city, in the county of NewYork and State of New York, have invented new and useful Improvements in Phonograpb Attachments, of which the following is a specification.

The general object of the invention is to effect the removal of particles of dust, d rt or the like, from the grooves or indentations of the surface of a sound record. Andto this end the invention'resides in providing ducer e.

a cleaner in the form of a brush and in adapting the brush to connect with any desirable portion of the phonograph, such as the diaphragm casing, and in adapting the connecting part of the brush to hold the brush in contact with thesurface of the sound record when thesaidconnecting part is attached to the phonograph.

Other objects will ap ear and be better understood from that lem odiment of my in vention of which the following is a specification, reference being had to the aocompanying drawings forming part hereof, in which:

Figure 1 is a perspective view of a portion of a phonograph showing my improved device connected to the diaphragm casing. Fig. 2 is an enlarged detail side elevational view of the diaphragm casing and showing' my improved device connected thereto. Fig. 3 is a rear elevational view of my improved device. Fig. 4 is a detail perspective view of the device showing the partsseparated. Fig. 5 is a detailed sectional view of the connectiombetween the brush handle and the pocket.

In the drawings a indicates a fragment of the casing of a phonograph, b the sound record and r: the casing for the diaphragm. d indicates generally the invention which is herein shown as connected to the casing c and arranged with such relation to the direction of rotation of the sound record I), as to be in advance of the stylus or repro- In the present embodiment the attachment is shown as used in connection witha disk sound record and a machine arranged to take such disk, but this-is simply illustrative and from what will hereinafter appear it will be readily understood that the invention may be used with other types of :sound records and machines adapted for use with these.

The clip formingone part of the subject- 1 inatter of the presentxlnventionfiand herein indicated. generally by f, is preferably -formed of resilient metal and comprises the jaws 55. 'These jaws are inspaced relation and the distance between them is-in such relation to the thickness of the casing c as to effect the further reading of the jaws during the act ofa justing the clip onto the casing a, which is doneby presenting the edge of the casing to the space be tween the jaws and forcing tliefclip over the casing, whereby to have the jaws friction all bind on the opposite faces of the casing and thereby support the clip against. accidental displacement. The "jaws are connected together by the walls, 6 and 7 of a pocket 8. This pocket8 is open at its lower I end and it is interiorly provided with a cross piecelfi in.the form of a lug which extends transversely. of the pocket.

10 indicates a brush stock which is equipped with relatively soft bristles 11.

The brush stock is'also provided with a ver tically disposed handle 12 adapted for insertion into the pocket 8 and having an. oblong, opening 13 adapted for receiving the cross piece 9. The presence of the cross piece in the oblong opcning 13 effects the suspending of the brush and when the brush is so snspended and the clip so adjusted on the casing c as to permit of contact between the end of the brush and the sound record,-

the surface of the record will be swept as the said surface passes under the brush. The presence of a spring 14 interposed hetween the pocket and the stock and herein shown in the form of a bow-spring and provided with an opening to receive the handle 12, operates to exert such pressure on the brush as will cause the bristles thereof to penetrate the grooves and indentations on the surface of the record. 7

Obviously- With this construction and when the brushis arranged as shown in'the drawingsand the record rotating; in the di rection of the arrow, the surface thereof will be cleared of all foreign matter prior to moving into contact with the. stylus. Consequently full efliciency of the record will be had by consequence of the removal of foreign material in the indentations of the recion To assemble the parts the handle 12 is inserted through the o ening in the spring 14 and the spring 14 is t en pressed out against the brush stock 10. The handle 12 is then 5 inserted in the pocket 8 and the cross piece 9 is passed through the registering opening in the pocket 8 and the opening 13 and then the brush stock is released whereby the spring draws the cross piece down against 10 the bottom of the opening in the pocket 8 and against the upper end of the opening 13.

What is claimed as new is: 1. In combination, a cli formed with a 15 pair of resilient jaw mein ers arranged in spaced relation, apocket located between the jaws, a support located in the pocket, and a brush located in the pocket and slidingly fitted on the support. I

2. In combination, a clip formed with a pair of resilient jaw members arranged in spaced relation, :1 pocket located between the jaws, a support located in the pocket, and a. brush located in the pocket and slidingly fitted on the support, and yieldingly held against movement in one direction.

In testimony whereof I affix inysignature in presence of two Witnesses.
